一、前言火山灰无熟料水泥及其硅酸盐轻混凝土作为应用地方材料和解决水泥不足等方面,具有很多优点。但是,由于该种材料大气稳定性较差,碳化后,强度一般都要降低,限制和影响了它的应用和推广。以往解决的办法是将制品进行蒸压处理,既需较大投资,又不利于大面积推广。然而,能否在现有抗碳化能力的基础上,采取措施进一步提高其

I. INTRODUCTION Volcanic ashless clinker-free cement and its silicate light concrete have many advantages as regards the application of local materials and solving cement shortages. However, due to the poor atmospheric stability of the material, after the carbonization, the strength is generally reduced, which limits and affects its application and promotion. In the past, the solution was to autoclave the products, which required a large investment and was not conducive to widespread promotion. However, on the basis of existing anti-carbonation capability, measures can be taken to further improve
